Repeating pistol

ABSTRACT

A repeating pistol wherein the sear is controlled by the trigger through an intermediate connecting link providing a clearance connection so that an idling motion may be imparted to the trigger before it releases the sear. The path or stroke of the trigger may be readily adjusted both forwardly and rearwardly independently of the adjustment of the pressure to be overcome when triggering. A manually operable lever is provided for lowering the intermediate connecting link so as to thereby disconnect the sear with respect to the trigger.

ln presently known pistols of this type, the pull off and strikingmechanisms fail to provide an adequate range of adjustments which may berequired by the marksman before firing. Furthermore, such prior artmechanisms are excessively intricate and delicate.

The repeating pistol according to our invention obviates such drawbacksin a manner whereby the adjustments performed prior to firing allow, insuccession, a modification in the pressure exerted on the trigger inaccordancewith the load applied, an adjustment of the stroke of saidtrigger independently of the pressure, an adjustment of the stopprovided at the front of the trigger so as to define its idling strokebefore it drives the sear through the agency of the intermediateconnecting link, and finally the adjustment of a return pressure exertedby a blade spring against the sear.

According to a further feature of our invention, th micrometric backsight is secured directly to a structure formed with the pistol body.

According to a still further feature of our invention, the movable boltor breech block is adapted to slide longitudinally with reference to thepivotal body and cooperating at its front end with a collapsible latchact ing as a stop so as to facilitate its dismantling or lock intoposition as required.

The setting of the pistol may be obtained by means of an intermediatesliding connecting link inserted between the sear and the trigger, withthe connecting link being provided with and displaying adjacent the rearof the pistol, a setting notch adapted to cooperate with a projection onthe sear so as to drive the latter, while a safety lever pivotallysecured to the pistol body is adapted to release the intermediateconnecting link.

According to a further feature, the stroke of a striker which isslidingly carried toward the rear of the movable breech block may beaccurately defined so that the striker may engage a collapsible stopposition vertically within the breech block, and to thereby lock thestop against movement.

The tang or shoulder engaging the palm, of the markmans hand is carriedby the grip of the pistol and may advantageously be adjusted so as toprovide a variable positioning thereof over a large range through theuse of an invertible supporting plate.

These features will appear, more readily in the following description ofan embodiment of our invention reference being had to the accompanyingdrawings, wherein:

FIG. 1 is a side view of the pistol, partly in section, the movablebreech block being shown in an operative position before firing, andwith the grip not being illustrated for clarity;

FIG. 4 is a view similar to FIG. 3, with the tang shown in a higherposition following a rotary motion of its supporting plate;

FIG. 5 is a longitudinal sectional view of the pistol, the movablebreech block shown in its rearmost retracted position prior to itsdismantling, as shown in interrupted lines;

FIG. 6 is a plan view, partly in section taken through line 5-8 of FIG.5;

FIG. 7 is an end view, partly in section through line C-C of FIG. 5;

FIG. 8 is a transverse cross-section through line DD of FIG. 5;

FIG. 9 is a perspective view of the collapsible latch;

FIG. 10 is a perspective exploded view of the striker in alignment withits collapsible stop.

As illustrated, the repeating pistol includes a unitary body 1 at thefront end of which may be securely fitted a pistol barrel 2 while itsrear end forms an enlarged structure I to the upper surface of which issecured a conventional micrometric sight.

The body I is provided with laterally extending longitudinal grooves Ialong which a movable breech block or bolt 3 is adapted to freely slide.The breech block bears against the rear end of the barrel and includesat its front end a depending rounded tongue 3 which slidingly engages alongitudinal U-shaped opening formed in the front end of the body 1. Aguiding rod 4 which is within an axial blind bore formed in the body 11is surrounded by a coil spring 5 which normally urges the breech block 3back into its operative position.

In its rearmost retracted position, the movable breech block 3 has itsguiding means 3 disengaged with reference to the above-mentioned groove1 in the body 1 whereby successive dismantling operations may beeffected by means of vertical releasing movements as illustrated ininterrupted lines in FIG. 5, and through a manually controlled sequenceso as to release the tongue 3 with respect to the cooperating opening inthe body I.

This dismantling is facilitated by a collapsible latch 6 adapted toslide vertically along one of the lateral surfaces of the body 1 whileits front surface 6 allows the extreme retracting motion of the breechblock 3 (FIG. 9).

When the latch is in its lowermost position (FIG. 1), its upper partforms a projecting tail-piece 6 2 defining the end of the stroke of thetongue 3 for which it provides a stop so as to prevent disengagement ofthe guiding means 3 on the movable breech block with the body isprevented and to thereby prohibit the dismantling thereof.

The latch 6 is held fast in each of its extreme positions by a ball 7which is subjected to the action of a spring housed within a hole formedin the body 1.

In the movable breech block 3, a striker 8 may slide axially, the rearend of the striker being formed into a cylindrical head. 8 one side ofwhich is cut so as to provide a flat-bottomed transverse groove 8, thelength of which, extending longitudinally of the striker, is designatedby X. The flab-bottomed groove may be shifted between the projectingedges of a corresponding U- shaped opening 9 formed in a detachable stopor plate 9 fitted vertically in a corresponding recess in the movablebreech block 3 (FIG. 10). It is noted that the length of the edges ofopening 9 is equal to a value Y which is smaller than the length X ofthe groove 8 so as to accurately define the longitudinal stroke of thestriker 8, and with the transverse edges of the groove 8 located insidethe opening 9 abutting against the transverse ends of the projectingedges of the latter.

The length of such a stroke is thus equal to X-Y as illus trated in FIG.5.

The front section of the striker 8 carries a coil spring 10 normallyurging the striker rearwardly. The spring is housed within a shoulderedchamber which is formed in the movable breech 3, and normally urges acylindrical section 8 of the striker head, lying to the front of thegroove 8 rearwardly into a chamber, having a corresponding diameter 9 tothe front of the opening 9 so as to provide a longitudinal fitting whichprevents, when the striker has been retracted an undesired release ofthe stop 9 within the movable block 3.

The release of the stop 9 is effected by pushing the striker 8 so as tomove its front section 8 out of the chamber 9 The body 1 is recessed inits upper rear part in order to form a housing for the rocking hammer 1l, the latter of which is pivotally secured to a spindle 12. The lowerend of the hammer is coupled by means of a pivot 13 with the end of apusher lever 14, about the outer end of which a coil spring 15 is wound,and the spring axially engaging a cleat 16 retained within a transverserecess of the body 1 by means of a pin 17.

Along its lower rounded edge, the hammer 11 includes a notch 11 which isadapted to be engaged when the pistol is being set, the projecting noseon a sear 18 being pivotally secured to a rod 19 which is rigidly formedwith a safety lever 19(FIG. l). l).

A spring 20 is inserted vertically in a blade recess formed in the body1 and shaped at its mid-length to provide a loop bearing on a transversepin 21. The upper section of the spring 20 is shaped so as to engage theupper front surface of the sear 18, while the opposite end of the springis urged into abutment with the body by the tip of a screw 22 positionedwithin a transverse dove-tailed cleat 23 in the body 1.

Through this arrangement it is apparent that the tuming of the screw 22by a predetermined amount produces a suitable tensioning of the lowerend of the spring 20, and consequently, an adjustable stress is exectedin the opposite direction against the sear 18 which is thereby thrustforwardly to ensure the required hooking engagement with the hammer 11.

It is noted that the screw 22 is provided at its outer end withlongitudinal grooves which cooperate with spring biased positioningballs housed within holes provided in the cleat 23.

It is further noted that the sear 18 extends transversely along theoutside of the body 2 so as to form a projection 18 cooperating with ahitch in an intermediate connecting link as disclosed hereinafter.

A trigger 24 is pivotally secured to the body at 25 and includes a head24 engaging a shaped groove in the body 1. The head 24 provides at itsend a permanent surface for a thrustexerting ball 27 which is housed inthe axial bore of a sleeve 26, the latter of which is longitudinallyscrewed into the front end of the pistol body 1. The action of a coilspring 27 urges the ball 27 towards the trigger head 24, and may beadjusted by a screw 28 screwed into the tapped bore of the sleeve 26, soas to provide for the adjustment of the pressure exerted on the trigger24 in accordance with the load prescribed for competition purposes.

Furthermore, the sleeve 26 is locked by means of a transverse screw 29threaded into the body 1. As in the case of the screw 22, the screw 28is provided with exterior longitudinal grooves which cooperate asillustrated in H6. 6 with the screw 29 so as to prevent an undesiredrelease of the screw 28. Thus, it is apparent that the adjustment of thepressure exerted on the tn'gger 24 is completely independent of themeans returning the sear into its inoperative position.

The head 24 of the trigger 24 carries a transverse sleeve 32 into whichis fitted a stud 30 which is rigidly connected with an intermediateconnecting link 30 so as to permit the latter to be shiftedlongitudinally.

The lateral connecting link 30(FIG. 1) 1) is provided at its rear endwith a U shaped notch 30 which engages the lateral projection 18 on thesear 18 so as to ensure the engagement of the latter. The length L ofthe notch 30 is, however, greater than the length D of the projection 18so as to allow the connecting link 30 to execute an adjustablelongitudined idling stroke without effecting movement of the sear 18.

It is noted that the continuous contact between the bottom of the notch30 and the projection 18 is obtained by a thrust in the direction of thearrow F, which is provided by a hairpin-shaped spring 31 secured to thesleeve engaging the pivot of the trigger 24, and with the upperresilient section of the spring 31 bearing against a transverse tongue30 formed in the front section of the connecting link 30.

It is apparent than upon firing a suitable gradual force exerted on thetrigger 24 provide for a shifting of the intermediate connecting link 30which executes an adjustable idling stroke, at the end of which the linkdrives the sear 18 in opposition to the action of the spring 20 so as toallow the nose therein to disengage from the hammer notch 11.

The hammer is thereby released and rocks so as to impinge against thestriker, the movable breech block being thereby moved into its operativeposition.

The idling stroke for the connecting link 30 may be adjusted by means ofthe front abutting point of the trigger 24, the point being defined bythe inner end of a screw 33 extending obliquely through the front end ofthe trigger so as to adjustably engage the registering in the body 1.The screw 33 is also provided with exterior longitudinal grooves adaptedto cooperate with a positioning ball. Similarly, the outer rear end ofthe trigger 24 is provided with an adjustable stop so as to provide fora pivotal motion having a predetermined amplitude, with the stop beingconstituted by a screw 34 the tip of which is also adapted to engage thecooperating groove in the body I.

In order to prevent the occurence of continuous firing in the event thatthe marksman leaves his finger on the trigger 24, it is necessary forthe connecting link 30 to automatically lower whenever the movablebreech block 3 is shifted, this action being facilitated by theengagement of a boss 30 on the upper surface of the connecting link 30with a longitudinally shaped groove formed on one side of the movablebreech block 3. A release in the direction of the arrow Fl disengagesthe notch 30 formed in the link from the projection 18 on the sear whichautomatically permits the sear 18 to be reset each time the hammerrecedes after firing. For providing the operative position of themovable breech block 3, the boss 30 on the upper surface of theconnecting rod engages a notch 3 in the breech block so as tointerengage the breech block and connecting link. The manuallycontrolled safety lever 19 which pivots a 19 coaxially with the sear 18,carries at its upper end a projection 19 (FIG. 5) adapted to shift theconnecting link 30 downwardly so as to release the latter by disengagingthe notch 30 in the link with respect to the projection 18. The lever isheld fast in either of its extreme positions by means of positioningballs, which are not illustrated.

Below the micrometric sight, an axial abutment rod 36 (FIGS. 1,6) islocated the flat free end of which registers with the hammer 11 so as tolimit the path followed by the latter. When set in the positionillustrated in interrupted lines in FIG. ll. Such an arrangement is ofinterest for blank firing, when the cartridge is not ignited. Actualfiring is executed after an unscrewing of the abutment rod 36, which isalso tensioned and positioned by a spring-urged ball, as shown in FIG.3, located within the rod and adapted to engage at least one recess inthe raised structure 1'.

According to our invention there is ridigly secured to one half of agrip 37 of the pistol, either on the righthand side or on the left-handside, a plate 3% which is provided with a T-shaped recess forming anannular slideway for a link 39 frictionally held in an adjusted positionby a screw 40. This link is rigid connected with a cylindrical lockingnut 41. This provides means for the vertical adjustment of the tang 43with respect to the grip section 37. This adjustment has a wide rangeand extends between the extreme positions in which the nut 41 securesthe link 39, as illustrated in FIG. 3 for the outer lower position ofthe tang 43 and in FIG. 4 for the inner upper position of thetail-piece.

Obviously the parts of the pistol which have not been described such asthe stop for the charger, the stop for the breech block when the chargeris empty and the foresight, are constructed in the usual manner known inthe art.
